Testing #zswap in #Fedora 19
Testing #zswap in #Fedora 19
Dietrich Schmitz would be interested in this...
One of the new features of the 3.11 Linux kernel was the zswap driver. When there is a need to start swapping zswap wil first try compressing data in memory. This will load the CPU with some compression/decompression, but will avoid slow writes to disk.
If you want to start testing zswap right now, these are the steps required:
First, install the required kernel. If Fedora still doesn't have a 3.11 or later kernel in the standard repo, try running
yum --enablerepo=\*testing\* update \*kernel\*
If this offers a 3.11 or later kernel you are set. if not, try installing the repo file for rawhide:
yum install fedora-release-rawhide
and then add the 3.12 or later from there:
yum --enablerepo=\*rawhide\* update \*kernel\*
Rawhide is more or less the alpha version of what will become Fedora.
Edit /etc/sysconfig/grub and add zswap.enabled=1 to the end of the GRUB_CMDLINE_LINUX line. then run
grub2-mkconfig -o /boot/grub2/grub.cfg
and reboot.
dmesg | grep zswap
will show some output if installation was successfull.
Leave a comment with your impression of zswap,

Why you should consider #Fedora as your #Linux platform.
Why you should consider #Fedora as your #Linux platform.
Let me be clear about one thing from the beginning. I don't think Fedora is the answer for everybody. But I want to list a few reasons why you should consider Fedora. And a few reasons to stay away.
Systems administrators: There is a high possibility you are dealing with Red Hat Enterprise Linux (RHEL) or one of its derivatives (CentOS, Scientific Linux...). Running Fedora on a desktop will give you the advantage that any new technology that pops up in RHEL will be old news to you. Fedora is sponsored by Red Hat and can be seen as a technology enabler/testbed for RHEL.
Software developers: You should definitely have a Fedora system in your build farm. Not in order to support Fedora, as you most probably won't, but to catch problems with new versions of kernels, libraries, etc early. That way you can prepare for code changes before you run into build problems on your supported platforms. Also, Fedora is clean. You have to add 3rd party repositories to get software that is encumbered by patents or other legal problems. By working on a clean Fedora platform you know when you introduce libraries that may not be free, and you can look into the legal ramifications.
Linux enthusiasts: Fedora has a big community. It also atracts a lot of developers. There are several reasons for that. One is that Fedora is close to upstream. The fedora way is to feed all changes and patches up to the upstream maintainers and make as few changes as possible to packages in Fedora. If you like to use your energy going forward instead of trying to halt progress Fedora may be for you. The red Hat involvement also means there are very professional developers on the team. If you really want to go beyond the bleeding edge you can enable the 'rawhide' repositories and run the 'rolling' alpha version of the next Fedora. Just be aware that rawhide may be best used in a virtual machine. rawhide breaks.
Let's look at the other side of the coin. Why should you not run Fedora?
If you think any distro needs to support LTS kernels, Fedora is not for you. Fedora will actually upgrade to newer major versions of the kernel within a Fedora release rather than use a lot of energy backporting critical fixes to older kernels.
If you are not familiar with linux, I am a bit uncertain. On one hand Fedora offers the latest versions of Desktop Environments (Gnome, KDE, LXDE, XFCE, Cinnamon, Mate...) with all the latest GUI bells and whistles to make a user friendly experience. On the other hand sometimes things break. Fedora is bleeding edge, so once in a while it can be nice to be familiar with a command line.
Fedora sometimes forces new technologies into production before they are quite finished. This helps shake out problems, but makes for some rough rides for Fedora users. Personally I prefer being part of that rather than figthing old and obsolete technologies. Among the most controversial such technologies were pulseaudio and NetworkManager. Both matured nicely.

no, i have not tried it. but it certainly looks fascinating.
